Grodziec [ˈɡrɔd͡ʑɛt͡s] is a village in Gmina Jasienica, Bielsko County, Silesian Voivodeship, southern Poland.

The village was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Grodische villa Snessonis.

Politically the village belonged initially to the Duchy of Teschen, formed in 1290 in the process of feudal fragmentation of Poland and was ruled by a local branch of Piast dynasty.

It was taken from them (as one from around fifty buildings) in the region by a special commission and given back to the Roman Catholic Church on 18 April 1654.

According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the municipality grew from 619 in 1880 to 569 in 1910, with majority of the inhabitants being native Polish-speakers (94%-97.6%) and minority German- (most 5.5% in 1900) and Czech-speaking (most 1.1% in 1890), and mostly Roman Catholics (91.5% in 1910), followed by Protestants (8.3% in 1910).
